ROOF.

Application led April 14,1921. Serial No. 451,228.' 1

To all whom it may comm:

Be it known that I, OsBonN L. HENDER- soN,A a citizen of the United States and a resident of Newport, in thecounty of2 Campbell and State of Kentucky, have invented certainnew and useful Improvements in Roofs, of which the following is a full, clear, and exact description, reference being had to i the accompanying drawings, Vforming-part edges of the courses held down by means of cleats.

It is the object of m invention to rovide a roof ofthe rol roofing in w ich the courses are .laid crosswise, as distinguisihed from lengthwise of the roof base, and'in which the edges of the rolls are joined together in a simple and effective manner.

us my invention involves primarily a novel form of-securing the edges of two iecesof material of liexible .nature which is specially adapted for use in the crosswise laying of composition roofing.

I accomplish my object by that certain construction and arrangement of parts to be vhereinafter more specifically pointedfout and claimed.

In the drawings, v

Figure l is a section taken through a roof` built according to my invention.

Figure 2 is a perspective of a roof on a A small scale showing the outer appearance presented by my novel roof.

The rooting to be utilized with my invention will be preferably of the type known as composition rooiing and as roll roofing, said material ordinarily being. made up of felt saturated with asphaltic or bituminous material and shipped in rolls for use as a covering for roofs and walls.

Thus I show strips 1, 1, of such roofing laid on the boards 2 of a roof structure. As heretofore indicated, the roofing is laid crosswise of the roof without overlap` one reason for this being that in view of the form of joint, if the roofingwere laid horizontally there would be a dam formed at each joint` reventing the flow of water 'olf thereof. l hen laid crosswise of a roof and joined together at the dges,roll roofing presents no impediment whatever to a direct flow of water. j

As shown, I provide a series of `metal strips 3 bent into a U-shape and."having formed in the central portion theredf a series of holes for nails 4. The strips also have thelrlower yedges beaded inwardly as The strips of rooling are laid in place-on the roof abutting each other laterally and the edges turned up for about a half inch in my preferred practice, as at 5, 5.

' The U-shaped strips ample to receive two flaps or folds 5 plus a roofing nail and when'the lstrips have been mounted and the edges Ibrought into abutment, the strips are set over the edges so'as to enclose them and the roofing nails then driven home into the boards of the roof.- In case a strip runs short and a lapping of the folds is necessary, three of the folds may be engaged by the strips 3'. If a nail be forced into the three folds, however, it will probably pierce the middle fold.

The result of this is to bring the sides of the pieces 3 down firmly against the roofing and the nails will find a passage between the are of av width just" roofing edges, so that they do not. perforate the roofing at all.

Any water which see s, past the tight abutment of the edges o the strips 3 with the plane surface ofthe rooling will not be able to pass up around the turned up portions, so that the joint will be a perfectly watfer .tight bond, extending cross-wlse of the roo The ymetal of 'the strips is not so stiff that it will not give slightly to expansion and when onestrip is not long enough to reach throughout a full length joint, the other pieces may be readily overla ped slightly and the joint sealed with pitch). The beads 3a press against and partially into the fabric without tearing it and thus hold it tightly in place.

I do'not find it necessary with this form of joint to seal with pitch, which makes unsightly humps in roofing of this type as it is generally laid, and when complete I preferably coat the strips 3 with asphalt paint or some such medium and sprinkle onto them the same sort of coating as is used with the roofing itself.

The important features of my invention are the provision of a tight joint. without overlapping, and without driving any nails through the roofing. In some weather I find it advisable to bend up the abutting edges of the strips prior 'to bringing them on the job, because in cold weather a careless operator might crack the body of the material-in forming the bend. y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A roof surface, comprising lengths of flexible roofing laid crosswise of the roof,

with the edges of the rooting bent upwardly Y and arranged in substantial abutment, and joining strips of channel form set over ythe upstanding edges, said strips being wide enough to readily receive two abutting edges of roofing, and nails driven down through the' channel pieces between the abutting edges of the roofing toI force thev upturned edges of the rooting material into -close engagement with the sides of the clamp pieces and at thel same time to secure the same to the roof.

2. A roof surface, compr1s1ng lengths of flexible roofing laid crosswise of the roof,

with the edges of t-he roofing bent upwardly andarranged in substantial abutment, and joining strips of U-shaped form set over the upstanding edges, said ystrips being of a width substantially equal to two thicknesses of roofing and nails driven down throuh 'the center of the strips and between the a utting edges of the roofing to force the upturned edgesl of the roofing material into close engagement with the sides of the lclamp pieces and at the same time to secure the same to the roof.

3. A roof surface, comprising lengths of flexible roofing laid c-rosswise of the roof, with the edges of the roofing bent upwardly andarranged inv substantial abutment, and joining strips of channel form set over the upstandingl edges, said strips being vwide enough to readily receive two abutting edges of rooting, and nails driven down through the channel pieces7 between the abutting edges of the roofingI to force thev upturned edges of the roofing material into close engagement with -the sides of the clamp pieces and at the same time to secure the same to the roof, said channel strips being of resilient metal.

41.-, A roof surface, comprising lengths of flexible roofing laid crosswise of the roof, with the edges of the roofing bent upwardly and arranged in substantial abutment, and joining strips of channel form set over the upstanding edges, said strips being wide enough to readily receive two abutting edges of roofing, and nails driven down through the channel pieces, between the abutting edges of the roofing to bring the edges of the strips tightly down against the plane surface thereof, said edges of the strips being beaded over along their lower edge with beads turned in so as to engage the rooting.
